7 Claims.

Coolers as heretofore made, for keeping bottles of charged liquids, suchas champagne, burgundy, ginger ale, beer, etc. properly chilled duringtheir service period at the table, have been quite cumbersome andexpensive as well as wasteful of the refrigerating agent.

The object of our invention is to provide bottle coolers especiallydesigned for use on the table in connection with charged liquids,whereby the charged liquids may be kept at the proper temperaturethroughout their intended service period, said bottle coolers beingattractive in appearance, readily handled, and inexpensive tomanufacture.

A further object of our invention is to produce a cooler of the abovecharacter which will be made of discardable material such, for instance,as paper board, which material will be so cheap that the cooler may bethrown away with its empty bottle, said cooler serving as a protectionfor the empty bottle, to prevent its breakage when thrown away.

Our improved bottle cooler comprises, generally, a refrigerantcontaining inner jacket and a heat insulated outer jacket and, moreparticularly, inner and outer jackets of the above character in whichremovable closures are provided for the jackets, whereby the refrigerantcan be placed in the inner jacket chamber and sealed therein, andwhereby the inner jacket may be inserted over the top of the table intoits refrigerating position and the outer jacket, without its closure,can be inserted over the bottoms of the bottle and inner jacket into itsinsulating position and its closure applied.

A practical embodiment of our invention is represented in theaccompanying drawings, in

which Fig. 1 represents a plan view of the bottle cooler in itsoperative position, embracing a bottle assumed to contain a chargedliquid;

Fig. 2 represents a side view of the same;

Fig. 3 represents a. cross section taken in the plane of the line IIIHIof Fig. 4;

Fig. 4 represents a vertical central section taken in the plane of theline IV-IV of Fig. 2;

Fig. 5 represents a top plan view of the closure for the inner jacketadapted to contain the re- 50 frigerant;

Fig. 6 represents a vertical central section taken in the plane of theline VI-VI of Fig. 5;

Fig. 7 represents a plan view of the inner jacket, with the closureremoved;

Fig. 8 represents a vertical central section taken in the plane of theline Fig. 7;

Fig. 9 represents a'top plan view of the closure for the outer heatinsulated jacket;

Fig. 10 represents a vertical central section 5 taken in the plane ofthe line X-X of Fig. 9; and

Fig. 11 represents'a vertical central section through the outer jacket,with the closure removed.

The bottle, which is assumed to contain a charged liquid, is denoted byl. Surrounding this bottle is an inner jacket having inner and outerside walls 2 and 3 forming an annular chamber 4 adapted to receive therefrigerant 5, which re- 15 frigerant may be shaved dry ice, forinstance. The inner and outer side walls of the inner jacket may besuitably spaced apart by an annular series of vertical strips 6, in thepresent instance four in number. These spacing strips 6. also serve tomaterially reduce the capacity of the chamber 4 and their widths may beadjusted, to provide a proper capacity for securing the right amount ofchilling eiTect of the refrigerant. The outer side wall 3 of the innerjacket is shown as cylindrical and the inner side wall 2 is shown astapered at its upper portion to substantially conform to the shape ofthe bottle I. This tapering of the inner side wall 2 serves also toprovide an annular hopper shape to the upper portion of the refrigerantcontaining chamber 4, thus not only enabling a larger amount of therefrigerant to be used at theportion of the bottle where it is mostneeded but also permitting the ready filling of the chamber with therefrigerant.

The annular closure for the inner jacket comprises in the presentinstance an outer top I having a depending flange 8 and an inner top 9spaced from the outer top by a heat insulating material, such forinstance as corrugated paper board H]. The tapered side walls ll of thecentral opening through the closure serve to snugly engage the taperedupper portion of the inner side wall 2 of the jacket when the closure isinserted into position to close the jacket, the depending flange 8 ofthe closure in the present instance overlapping the top of the outerside wall 3 of the inner jacket.

The outer heat insulated jacket is herein shown as comprisingcylindrical side walls I2 and a closed bottom l3 lined with a heatinsulating material such, for instance, as corrugated paper board M.

The annular closure .for the outer jacket comprises, in the presentinstance. an outer top I 5 VIII-VH1 I or 2 provided with a dependingannular flange i6 adapted to snugly fit over the top of the side wall Hof the outer jacket. An inner top I! is spaced from the outer top l5 bya heat insulating means such, for instance, as corrugated paper boardHi. The tapered side wall IQ of the central opening through the closurehas attached thereto a tapered yielding washer 20 which is adapted tosnugly embrace the neck of the bottle when the parts are assembled. Thistapered washer may be of rubber, felt, or other suitable material.

In operation the parts of the cooler and the bottle are assembled asfollows:

A refrigerant is placed in the chamber in the inner tubular jacket andthe closure is placed in position to close the said chamber, it beingobserved that the bottom of the tubular jacket is open. The inner jacketis then inserted over the top of the bottle until the tapered inner sidewall 2 comes into snug engagement with the tapered portion at the neckof the bottle. The heat insulated outer container is then insertedupwardly over the bottom of the bottle and inner jacket and the closurefor the outer jacket is inserted downwardly over the top of the bottleinto position to close the and bring the yielding tapered washer 20 intosnug engagement with the neck of the bottle above the closure for theinner jacket.

When the parts are assembled the bottle with its cooler is ready for useand may be placed on the table or counter, the refrigerant serving tokeep the liquid within the bottle chilled to the proper temperature fora considerable period of time, at least long enough for the normalserving of the entire contents of the bottle.

It will be noted that the bottom of the inner jacket is spaced somewhatfrom the bottom of the outer jacket, thus rendering the coolerapplicable for bottles of various heights within reasonable.

limits.

The cooler may be made of discardable material such, for instance, aspaper board, so that it may be made cheaply enough to warrant its beingthrown away with the empty bottle. After this is done the cooler servesthe additional purpose of protecting the empty bottle from breakage whenthrown into an empty bottle receptacle. This is an important point, forthe empty bottles of the more expensive wines especially have aconsiderable market value. It is, of course, obvious that this coolermay also be made of permanent materials so that the cooler may be usedrepeatedly, thus rendering it feasible for use in households where alarge number of coolers would )t be required to be kept in stock, as isrequired in hotels and restaurants.

It is evident that various changes may be resorted to in theconstruction, form and arrangement of the several parts withoutdeparting from the spirit and scope of our invention, and hence we donot intend to be limited to the particular embodiment herein shown anddescribed, but
